Terrain Grid System 2

Drop a fast, interactive grid onto any terrain, mesh or object, then highlight cells, mark territories and move units with built-in A* pathfinding. Terrain Grid System 2 is the grid layer strategy, RTS and tactics games need, ready in seconds.

Working on a strategy or RTS game and need to highlight cells under your units or show controlled territories?

Want to let the player pick a destination over a terrain?

Or just need a clean interactive grid over any terrain or mesh? This is the asset for that.

FITS ANY SCENE

• Easy to use: add the Terrain Grid System script to your terrain, object or group of objects to attach and configure the grid instantly, or drag & drop the prefab to run stand-alone (no-terrain mode).
• Works with Unity standard terrain (single and multi-tile), mesh-based terrains, or any GameObject with a mesh.
• Multiple grids per scene and multiple grids per terrain.
• Smart positioning: scale and fit inside terrain bounds, max slope, min altitude and more.
• Configurable grid types: Voronoi tessellation, box/squared, rectangular and hexagonal, producing an optimized low-vertex mesh.

HIGHLIGHT AND SELECT, FAST

• The fastest selection and highlighting system for both cells and territories.
• Coloring and fade-out for cells and territories.
• Rectangle selection with click & drag.
• Change visibility, color or texture of cells right in the Unity editor with the integrated grid editor.
• Control individual cell visibility via API or an alpha texture mask.

REAL PATHFINDING FOR UNITS

• Multi-threaded A* pathfinding within single or interconnected grids (boxed and hexagonal), with custom cell weights and obstacles.
• Supports large units that occupy more than one cell (minimum clearance option).
• Define blocking cells or assign cells to groups (zones, obstacles, custom navigable paths).
• Query neighbours or cells in range by crossing cost, max steps or cell group masks.
• Line of Sight (LOS) functions included.

DESIGN YOUR TERRITORIES

• Two levels of regions: cells and territories.
• Define territories from a color texture or directly in the embedded grid editor.
• Merge cells and manage regions through the API.

TECHNICAL & DEVELOPER

• Works alone (planar grid), with Unity terrain, and with mesh-based terrains.
• Works with orthographic and perspective cameras.
• Extensive C# API for grids, selectable cells/territories, neighbour queries and cell merging.
• Full C# source code included.
• 35+ demo scenes with useful sample code.
• Compatible with Built-in, URP and HDRP pipelines.
• Compatible with Unity 2022 and Unity 6, including Render Graph.

Add it to your terrain and have a working tactical grid in minutes.
